What is the fiftieth term of the arithmetic sequence 3, 7, 11, 15, ?

199

Step-by-step explanation:

For this problem, you have to write an formula.

a(n)=a(1)+(n-1)d

n is the term you are trying to find (in this case it's 50).

a(1) is the first term in the sequence (in this case it's 3).

d is the common difference (in this case it's 4).

Plug those in, and you get:

a(50)=3+(50-1)4

And you can easily solve that and get a(50)=199.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
